NHTSA Crash test ratings are performed to adequately make sure that whatever vehicle you are riding in, is both safe and secure. Crash test dummies are placed into the car and a variety of tests are done to generate NHTSA Crash Test Ratings. The vehicle crash test ratings that arise from the NHTSA crash tests are done in star ratings. The NHTSA crash test ratings are similar to movie ratings in the grand scheme of things. The lower the star, the less safe the SUV or truck is.

Front, side impact and rollover tests are performed on each vehicle, by placing the crash test dummies into the car and creating various real-life experiences that could occur on the road. In the frontal test, dummies are placed in the front seat and the vehicle is driven into a barrier at 35 miles per hour and then the damage is assessed. For the side impact tests, the dummies are placed into the vehicle, and then the NHTSA simulates a collision in an intersection. Rollover tests, currently the only test considered in NHTSA crash-test ratings uses a mathematical method and combines the weight of the vehicle, the center of gravity and the width of the vehicle to determine whether the vehicle is likely to rollover. The NHTSA will then assess the damage to the crash test dummies and the SUV or truck to generate a rating. Ratings are done on SUVs, trucks, vehicles, and car that pack acceleration into themselves such as the top fastest cars. NHTSA crash test ratings help consumers in their decision to buy a SUV or truck, or a vehicle period.
